"Margaret 1887-1945 married Joseph Hebein 1885-1958"
A death notice was published in the local German newspapers for Margaretha Kavalar Hebein. This may or may not be of interest your research.
Publishing of the German language papers left Milwaukee for Chicago shortly after 1950, although there was still a Milwaukee readership. The later papers can be accessed, but by special request to view bound volumes as they are not also part of the local microfilm collection.
